Coulombs law is given by the equation:F=kq1*q2/r^2 This means that the force of attration between two particles is = to k(9.11810^9) times the product of their charges divided by the distance apart sqaured. The final units are in Newtons. And in this equation k is a constant given by: 9E9 N*m^2/C^2
The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.
Coulomb's law is used to calculate the electrostatic force between two charged particles. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The "Q" in Coulomb's Law represents the magnitude of the point charges involved in the interaction. It is the charge of one of the point charges that determines the strength of the electrostatic force between them.
The variable for charge in coulombs is typically represented by the letter "Q".
A statement that is not true for Coulomb's law is that the force between two charges depends on the type of material the charges are made of. Coulomb's law only depends on the magnitude of the charges and the distance between them, not on the material properties.

Limitations of coulombs law
No
Newtons law has to due with mass and ATTRACTION only Coulombs law has to due with charge and ATTRACTION AND REPULSION
To calculate the amperes when given coulombs, use the formula: Current (I) = Charge (Q) / Time (t). If the time is not specified, you can't determine the current from just the charge in coulombs.
(4 coulombs / 2 seconds) = 2 coulombs per second = 2 Amperes.
Amps are coulombs per second, and there is no information on rates given here.

The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.
calulate the voltage of a battery that provides 20 joules of energy to every 5 coulombs of charge
Coulomb's law is used to calculate the electrostatic force between two charged particles. It states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The charge transferred in 25 minutes by a current of 500 mA is 750 coulombs. Amperes is defined as coulombs per second, so 500 mA is 0.5 coulombs per second. 25 minutes is 1500 seconds, so the charge is 750 coulombs.
